Square API Integration Services

Granite Web is a provider of Square Payment API integration services for WooCommerce and custom web applications.

You can use Square to accept payments from any cards with the Visa, Mastercard, American Express, Discover, JCB, or UnionPay logos. You can also accept any gift card or prepaid card with the same logos mentioned above, as long as the amount of the charge does not exceed the balance on the card.

Every card has the same flat rate. Corporate, prepaid, gift cards, and rewards cards have no additional fees, and debit cards are run just like credit cards (you do not need to enter a PIN).

We provide integration services for the all Square APIs including:

  • Square Checkout API
  • Square Payments API

Square Payments API

Square’s Payments API is a payment solution that allows you to accept credit and debit card payments from your own website. Customize your own payment form and checkout experience to accept payments with Square.

Square Checkout API

Square Checkout API lets merchants accept online payments for supported payment types using a checkout workflow hosted by Square, simplifying the process of accepting online payments. Once it’s time to collect the payment, buyers enter Square’s hosted checkout flow and return back to your website once the payment is complete.
